The use of obd gps tracker is now more extensive, and more people use it. At the same time, there are many misunderstandings about obd gps tracker on the market. More and more people believe this kind of misunderstanding, so that they feel that the obd gps tracker they bought is not the same as what they imagined. This kind of misunderstanding that has been formed for a long time, today I will discuss with you one or two.

One: GPS can be positioned anytime, anywhere?

The obd gps tracker does not have signals everywhere, and there are many influencing factors that interfere with the locator to complete satellite signal reception when the signal is insufficient. Predictable such as trees on the street, invisible such as electromagnetic waves, etc., these are the normal signal searches that affect the obd gps tracker.

Even so, there are solutions. For details, please refer to the previous article "Why do GPS positioning and LBS positioning appear at the same time?" ". But even then, there will always be places where neither signal is present. So it is not accurate to say that obd gps tracker can locate anytime, anywhere.

Two: The obd gps tracker signal map shows the signal quality of the device?

When people buy obd gps tracker offline, more and more merchants will explain the signal quality of the device to you based on the number of device information displayed on the computer platform or APP. Indeed, according to this method can be used as a basis for identification, but it is not absolute. What's more, there are still many merchants who will make this signal value look more contagious according to some modified software. Therefore, when purchasing, you should not believe this statement too much, and you must have your own judgment and choose from other aspects.

Three: More and more obd gps trackers that can locate indoors?

As mentioned above, there are many factors that affect the locator signal, and one of them is the skyscrapers that are common in our daily life. Indoors, also in the building. Since such buildings are covered with concrete and metal, the signal cannot pass through. Except the window can receive the signal. Most of the signals that you can see indoors are actually from LBS base stations or Wi-Fi positioning. These three positioning methods have their own advantages and disadvantages, and according to the current technology, it is temporarily impossible to change their original characteristics.

Four: Is there an obd gps tracker without a card?

This is also the biggest rumor. The said card-free locator does not mean that no card is inserted, but the manufacturer has built the card into the device according to the needs. Without the card, the device has no signal, and the signal transmission cannot be completed. And if such a card-free locator fails, the subsequent maintenance is also very troublesome, which greatly affects the experience for users.

Finally, I suggest that you should not only consider a single factor when deciding to buy an obd gps tracker, but remember to prepare your homework in advance. It is best to choose a big brand, and professional sales staff will tell you the suitable model before purchasing, and then the service guarantee will be more comprehensive.
